.1 This. invention, relates to a form locking-up device, and. its.principaljobjeot is to provide improved lock-up mechanism for locking upprinting forms and at the sametin e to dispense with printers quoins,printers furniture or otherlockup material, in thelocking up of formswithin or without a printers chase, press, galley or the like. 7 Anotherobject is'to provide improved lockingup mechanism that can be adjustedto fit any printer's chase, press, galley orthe likewithout in any wayaltering the manufactured form of any of these devices. i

Another objectis'to provide improved lockingup mechanism that enablesforms "to be locked up without any strain or stress upon the chase orpress; the strain going against the form.

Another objectis to lock the lock-up means in the adjusted'positionthereof, wherebyvibration or jars cannot loosen the locking bars fromtheir hold against the form or typefa nd-caii be locked up at anypredetermined position in the chase or press. i

With these and. other objects and advantages in view, this'inventionconsists inthe several novel features hereinafter fully set forth,andlmore particularly defined in the-appended claims. T

Inthe stub shafts. 32,

35 are formed sockets 40, 4|. into which a wrench li xor the i l fle sRi h in ert for the purpose of rotating the pinions. The socket 45 is ofgreater diameter than the socket 4|, whereby one tool may engage in thesocket 443 and rotate the pinion 24 without rotating the pinion, and atool of lesser diameter may enter the socket 4| to rotate the pinion 25without rotating the pinion 24. Rotation of the pinion 24 in onedirection moves the slide 22 along the lock-bar I2, and rotation of thepinion 25 moves the slide along the lock-bar I3.

Each lock-bar is preferably provided with a longitudinal extendinggroove 43, in which travels a lug 45 which projects from the slide. Thegroove end lug connections provide means for guiding the slide to movealong both look bars.

The slide is further provided with two sets of locking means designatedgenerally by the reference character 46, to lock the slide to each ofthe intersecting lock-bars associated therewith, whereby to preventvibration from loosening the lock-bars from the form. As shown, eachlocking means comprises a worm 46 rotatably mounted between cars 42, 41,which extend up from the base of the slide. A headed pin or screw 49extends through the worm and through slots 50 in the ears 4'2, 41. Theworm is moved toward and away from the teeth of the racks by ayokeshaped finger piece i, having arms 52 pivotally mounted on the pin49, and having curved slots 53 non-concentric with respect to the pin54. The pin 54 is secured in the ears 42, 41 of the slide and extendsthrough the slots 53 in the arms 52, and causes movement of the arms andtherewith the pin 49 and worm 46 toward and away from the lock-bar rack.When the finger piece is swung downwards to the position seen in Fig. 5,it moves the worm 46 toward and into mesh with the teeth of theassociated rack. The teeth of the worm are helically disposed thereon toenable them to be meshed with the teeth of the rack in any adjustedposition of the slide, and

the teeth are notched at several places around their circumference tofacilitate turning the worm into mesh with the teeth of the rack. Ifdesired, the threaded pin 49 may be threaded in one of the arms of thefinger piece so that by turning up the threaded pin tightly, the fingerpiece will be clamped against movement.

In operation the lock-bars are moved up against the form, and thepinions rotated to bring the lock-bars tightly against the form, and thefinger pieces are then depressed, thereby meshing the worms'with therack teeth.

In the modified form of the invention, illustrated in Figs. 8 and 9, theform ll is surrounded by type high foundry bars 60. In this form of theinvention the lock-bars I2 and I3 are of the same thickness, so that onemay lie above and across the other, their ends being formed with heads6|, in which are secured threaded stems l8, upon which are threadeddiscs I9, as in the preferred form.

The lock-up means 2| is constructed substantially in the same manner asthe corresponding lock-up means of the preferred form of the invention,and the form locking-up device is secured in a chase In, as in thepreferred form. This modified form of the invention is shown as appliedto a foundry form.

In the forms of the invention hereinbefore described, double lock-updevices are providedthat is to say, the double lock-up means operates ontwo lock-up bars.

In the form of the invention illustrated in Figs.

10 and 11, a single lock-up device 2l is illustrated in connection witha short lock-up bar I2 which bears against the lock-up bar I3 In thisform of lock-up device only one pinion 24 is employed, which meshes withthe rack teeth of the lock-bar I2 This form of the invention isillustrated in connection with a foundry form, in which the .form I Itis locked in place in the chase. 60 designates type high foundry barsthat surround the form.
